To all whom it may concern:

Be it known that I, HARRY NEWBOLD, a subject of the King of GreatBritain, residing at St. Albans, in the county of Hertford, England,have invented certain new and useful Improvements in Eyeglass-Mountings, of which the following is a specification.

My invention relates to mounts for rimless eyeglasses and has mainly forits object to provide an improved form of adjustable lens strap or clampwhich can be adapted to mounts of different types, and which enables anymount to take lenses of different thicknesses.

According to the invention I provide a lens clamp or strap comprisingtwo bearing pieces or jaws each of which 18 made so as to bear againstone face of the lens and also to embrace the periphery thereof, theportions of the two jaws of each strap or clamp which bear upon the lensperiphery also engaging with one another, but in such a manner that thedistance apart of the jaws can be adjusted as required.

The improved strap can be utilized in combination with fittings ofdifferent types. For example, it can be applied to rimless eyeglasses ofthe kind known as finger piece eyeglasses, in which case the end of thebridge carrying the post or pivot for the fingerpiece lever is solderedor attached to the endof one of the interlocking jaws of the strap. Or,the improved strap can be adapted to rimless eyeglasses of'the kind inwhich the placquets or guards are opened outward or extended by thehorizontal outward bending or turning of the lenses. In this case thecomplete mount may advantageously be made of three pieces, one piececomprising the bridge and having at each end a portion constituting onejaw or half of the lens strap or clamp, and the other two pieces eachconsisting of the other half or jaw of the lens clamp or strap and theplacquet arm and placquet.

In carrying out the invention one of the parts or jaws of the strap isformed at that part which embraces or bears against the periphery of thelens with a slot, the corresponding part of the other half or jaw of thestrap passing through and thus interlocking with the said slottedportion in such a manner that the two parts can be adjusted relativelyto one another, so as to take lenses of different thicknesses.

To enable my invention to be fully understood I will describe it byreference to the accompanying drawings, in which Figure l is a back viewof a pair of rimless eyeglasses of the finger piece type, and providedwith adjustable lens straps of the kind above referred to. Fig. 2 is aplan view thereof. Fig. 3 is a section on the line 8-3, Fig. 2. Figs. 4and 5 are plan views respectively of the two parts or jaws of the strap.Fig. 6 is a perspective view drawn to a larger scale showing thecomplete strap. Figs. 7 and 8 are views showing the two halves of thestrap developed. Fig. 9 is a section on the line 9-9 Fig. 3 drawn to alarger scale. Fig. 10 is a view similar to Fig. 9, but illustrating amodification, and Fig. 11 is a plan view of a portion of a pair ofrimless eyeglasses illustrating a slight modification in the strap. Fig.12 is a view similar to Fig. 1 showing the invention applied to a typeof rimless eyeglass in which the placquets are opened out by thehorizontal bending of the lenses. Fig. 13 is a plan view thereof. Fig.1a is a section on the line 1414, Fig. 12. Fig. 15 is a plan view of oneof the placquet stampings. Fig. 16 is a similar view of a portion of thebridge stamping. Fig. 17 is a view of the bridge piece as stamped fromthe blank and not bent to its final form, and Fig. 18 is a similar viewof one of the other placquet stampings.

Referring first to the arrangement illustrated in Figs. 1 to 11 (1represents the lenses and b the bridge having the posts or pivots bcarrying the finger piece levers 0 and placquet (Z, all these partsbeing of ordinary construction. a and f are the two halves or jaws ofeach strap which bear respectively against the two opposite faces of thelens a to which they are secured in the ordinary manner by means of ascrew 9 passing through them and the lens. The end of each of thesehalves or jaws is bent at right angles so as to bear against or embracethe periphery of the lens as clearly shown, this portion of the half orjaw 6 being slotted as shown at e and the corresponding portion f of theother half or jaw f being in the form of a tongue which is designed topass through and thus interlock with the slotted portion 6 of the firstnamed half or jaw. It will thus be seen that while the two portions ofthe strap are interlocked as stated they can be adjusted relatively toone an other to take different thicknesses of lens. The slotted portion6' is formed with lens bearing strap which serves to hold the lensrigidly in the mount.

In the construction illustrated, the end of the bridge 6, immediatelybeyond the post or pivot Z), is soldered to the tongue 7" of the straphalf f, but it will be obvious that it can equally well be attached tothe slotted portion aof the other strap half.

In practice, to effect a more eflicient interlocking of the two parts 6and f of the two strap halves, I may form the interlocking faces ofthese two parts with a bevel or with inclined faces h as shown in Fig. 6and Figs. 9 and 10. My improved lens strap also lends itself whenapplied to this type of:

.rimless eyeglass to the ready adjustment of the lens to suit difierentpupillary measurements. For this purpose the end of the strap half towhich the bridge is attachedin the case illustrated the end f of thestrap half f--can be extended and turned back as shown in Fig. 11 to anydesired extent, thus adjusting the position of the center of the lensrelatively to the center of the bridge to suit requirements.

Figs. 12 to 18 illustrate the application of my improved lens strap tothe form of rimless eyeglass in which the lenses can be turned in ahorizontal plane upon a vertical axis, so as to open or extend theplacquets, the mount in this case being formed in three pieces inclusiveof the lens straps. v

64 represents the lenses, and b is the bridge portion of a steelstamping, the said bridge Z) having at'each end the part c formed withthe slot 6 carrying the lens bearing strap 0 Fig. 17 shows this part asstamped from a fiat sheet metal blank and Fig. 18 is a similar view ofone of two other stampings which consists of the placquets g and theplacquet' arm 72. to one end of which the placquet g; is attached andthe other end of which terminates in the strap half or jaw f.

The bridge stamping shown in Fig. 17 is bent in the manner shown inFigs. 12, 13 and 1 1 and 16, that is to say, the part 6 having the slot0 is bent round at right-angles to the bridge 5 and the jaw is then bentat right angles to the slotted part 0 so that it comes to lie in a planeparallel to that of the bridge Z). Each of the other stampings is alsobent in asimilar way, that is to say, the end of the arm it having thejaw f is bent round at right angles to the said arm 71/ and the placquetg is turned round upon the said arm to the position shown so that itcomes to lie parallel to the side of the wearers nose. 7

To fit the mount to a pair of lenses the arms 72, of the two placquetstampings are passed through the slots 6 of the bridge stamping so thatthe two jaws e and f at each end of the bridge form the clamps intowhich the lenses can be inserted and in which they are secured by meansof the screws 9 which pass through holes provided for the purpose in thestraps and in the lenses, the parts 6 and 71. of the two stampings whichbear against the periphery of the lenses interlocking as clearly shown,so that not only are the lenses securely held in place but the threeparts of the mount are connected to form a whole.

In practice the interlocking parts of the. lens strap may be made withbeveled or inclined edges as described with reference to Figs, 1 to 11.Furthermore, the slotted portion 6 of the strap may be formed with abridge piece y', shown in broken lines in Fig. 17, the object of whichis to provide an additional means of retaining the interlocking parts inengagement.

Having now particularly described the nature of my said invention and inwhat manner the same is to be performed, I de clare that whatI claim isI 1. An eyeglass mounting consisting of ice three metal stampings, onestamping com- I prising thebridge having at each end a half or par-t ofthe lens strap which bears against the side of the lens, and has aslotted portion which embraces the peripheryof the lenses, and the othertwo stampings each consist of a placquet and a placquet arm terminatingin the other half of the strap which bears against the lens peripheryand interlocks with the aforesaid slotted portion.
